The modem configuration string is an AT command that
allows the modem to be compatible with
MicroTech control-
lers. This configuration is set at the factory. If a problem with
configuration occurs, the configuration string may need to
be reset. To reset the string, a PC using the correct com-
munications software is needed. Refer to the US Robotics,
WorldPort User’s Guide for more information on resetting
the string.
The following AT command is used to configure the
modem:
AT&FS0=1 B0Q1 E0&D0&W. Table 6 explains
each command of the string.

Note: For high speed modems, flow control must be
disabled to make the modems
MicroTech compatible. In the
WorldPort 14.4K modem, flow control is disabled as a fac-
tory default. No additional configuration is needed beyond
AT&F.
Remote Access
Using a PC and communications software, the modem can
be set up to be configured by a remote modem. This can be
helpful in troubleshooting modem operations. This enables
the user to call into the modem from a remote site and
change the configuration. For complete instructions on how
to perform Remote Access, refer to the US Robotics
WorldPort High Speed Modems User’s Guide (Appendix E).
